Product name: HCR3102A Transformer DC resistance tester
Category: Transformer comprehensive test series
Detailed introduction
Product Introduction
HCR3102A is a fast test equipment for measuring the DC resistance of transformers, mutual inductors, generators, motors and lines, and is a replacement product for single-arm and double-arm bridges.
Functional characteristics
Two power supply modes are adopted: AC220V power supply; internal lithium battery power supply;
With perfect reverse electromotive force protection function;
With charging and power display functions, large-capacity lithium battery is adopted to meet the needs of field tests;
For the longitudinal test of DC resistance of on-load tap-changing transformer, power supply can be completed at one time;
The measurement speed is fast, and the measurement data is accurate and stable;
With the characteristics of simple operation, high precision, anti-interference, shockproof, easy to carry, etc.;
Suitable for fast measurement of DC resistance of transformers with voltage levels of 110kV and below.
